IMPROVEMENT IN WAGON-JACKS.

Specification forming part of Letters Patent No. l7,63, dated March 14,1876 application filed September 7, 1875.

To all whom it may concern Be it known that I, AUGUSTUS T. Jonas, ofStamford, in the county of Fairfield and State o Connecticut,haveinvcnted certain new and useful Improvements in Wagon-Jacks; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawing, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in wagon-jacks; and consists in theconstruction and arrangement hereinafter fully. described, and pointedout in the claim.

In the drawings, Figure l is a side elevation. Fig. 2 is an end viewwith one leg folded up. Fig. 3 is a top view with both legs folded, andFig. 4is an end view with both legs pendent.

a is the lever by which the axle is raised. 011 its upper side, near theend a, which is placed under the axle, is formed the notch a having thestraight sides a c placed at an obtuse angle to each other, and so thatthe angle a", when the end a of the lever a rests on the ground, shallbe immediately over the pivotal center of the legs hereinafterdescribed. When the end of the lever arests on the ground, asshown inFig. 1, the side a is in a horizontal line. The notch a is plated withthe metal strap a to protect the wood, and on the end of the strap isturned up the flange or projection a, which prevents the axle, whenraised rapidly, from being thrown off the side a b is a round mortise,cut through the lover a to receive the pins in the legs, as hereinafterexplained. a c are the legs, pivoted at c to the lever a. They are madeof different lengths that the jack may be adapted to both the front andrear axles. c are pins driven into the legs 0 c on the inner sides ofthe latter, and so placed that, when the legs are folded up alongsidethe lever, they will enter the round mortise b and retain the legs inthat position.

In use, one or the other of the legs is folded up, according as it maybe desired to raise the higher or lower axle.

When it is desired to put the jack away both legs are folded to the sideof the lever, thus putting the implement in small compass.

In raising a wheel the lever to is lifted sutliciently, so that thestraight side a of the notch (t can be placed under the axle. The leveris then pressed don 11 till the end a rests on the ground, whichmovement causes the axle to pass from the side a to the side a andbrings the center of gravity of the axle between thelegs c c and the enda of the lever a. The projection c prevents the axle from being jarredor knocked backward off the horizontal side a Having described myinvention, What I claim, and desire to secure by Letters Patent, 1s

The lever a, having the notch c constructed as described, projection to,mortise 1), legs 0 c and pins 0 all constructed and arrangedsubstantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I at'fix mysignaturein presence of two witnesses.
